HFS + file system volumes comprise different metadata information like volume header, allocation file, catalog file and many others. All such data structures are defined on various sectors of hard disk volume. In HFS+, volume header is actually a replacement of MDR of HFS file system which keeps all volume metadata within it. However, if metadata structure gets corrupted or faces consistencies, it may result in corruption of your important file system.
Let us consider in a practical scenario, when you try to boot your Mac OS X and access data from the HFS+ file system volume, you may come across the following error message:
“HFS+ partition Error”
HFS+ partitions make use of Apple Partition Map (APM) as its partitioning scheme. This error is mostly caused due to incorrect partitions schemes or hard disk errors. You will generally face this type of error message on dual-boot systems, mostly with GRUB. Moreover, you will also face difficulties to boot up your macbook if the corrupted volume is a startup volume.
In order to resolve this error you may use disk utility or fsck command for detecting the hard disk errors as well as repairing them. You should also check if GRUB is correctly installed over your system or not. If it is not properly installed, reinstall it. If you are still facing the problem, partitioning scheme may be the cause of this error. Inaccurate starting sector partitions may be the reason behind this error. So if you repartition the hard drive by changing partitioning scheme, hfs+ partition error can be fixed. After repartitioning, your crucial data will be lost, so you have to take the help of a valid backup for restoring your crucial data.
But, in the absence of a valid backup you will have to take the help of third-party Mac data recovery tools available in the market for retrieving your lost data and information. These third-party applications easily and securely recover lost data from the macbook hard drive from almost all data loss situations. It is capable of recovering lost data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. This software supports Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.
